Linearly wound fork spring from YSS in a firmer version than original. The YSS fork spring is made of silicon spring steel. This can reduce the wire thickness, which has a positive effect on the spring properties, but at the same time avoids torsion of the spring. The spring is delivered top and bottom sanded. The scope of supply includes a fork spring for a fork leg (only valid for Showa forks which are factory-equipped with only one spring).
